The packet rate limiting method and system is used for detecting and blocking the effects of DoS attacks on IP networks. The method uses an ACL counter that stores an action parameter in the first 3 most significant bits and uses 13 bits as a packet counter. A rate limit is enforced by setting the packet counter to an initial value, and resetting this value at given intervals of time. The action parameter enables the ACL to accept or deny packets based on this rate limit. If the number of packets in the incoming flow saturates the packet counter before the reset time, the packets are denied access to the network until the counter is next reset. The denied packets may be just discarded or may be extracted for further examination.

The invention discloses a device and method for collecting and storing microorganisms in frozen soil. The cantilever is released, the cantilever moves downward under weight, the drilling assembly drills the well and breaks the soil vertically, and the frozen soil isolation assembly and the drilling assembly move down synchronously to break the drilling assembly. Frozen soil isolation prevents cross-contamination; the drilling assembly moves down to the deepest position and stops rotating, connects the frozen soil isolation assembly with the power assembly of the drilling assembly, uses the rotating crankshaft of the drilling assembly to drive the rotation of the frozen soil isolation assembly, and uses the power assembly to drive the frozen soil isolation assembly The frozen soil storage point on the frozen soil is opened; the power assembly of the drilling assembly is stopped from rotating, and during the inertial rotation of the frozen soil isolation assembly, the power assembly drives the frozen soil storage point on the frozen soil isolation assembly to close; the cantilever is lifted to drive the drilling assembly and The frozen soil isolation components move up synchronously to complete the collection and induction of frozen soil; the invention realizes the collection and storage of frozen soil and its internal microorganisms during the drilling and crushing of frozen soil, improves efficiency and avoids cross-contamination of frozen soil microorganisms.

The present invention relates to an electrochemical measurement device, in particular to an electrolytic cell device based on the on-line electrochemical measurement of the transmission line, including an electrolytic cell, a fixing clip, etc., wherein the electrolytic cell includes an electrolyte container with an upward opening, a square The connecting part of the partition and the workpiece, the square partition is located between the electrolyte container and the connecting part of the workpiece, and its periphery protrudes to form a square ring-shaped boss; the connecting part of the workpiece is a columnar member, which is opened along the central axis of the connecting part of the workpiece It has a cylindrical through hole, and the cylindrical through hole passes through the workpiece connection part and the square partition and communicates with the inner cavity of the electrolyte container. The advantage of using this device is that it does not need to destroy the workpiece of the transmission line, avoids adverse effects on the transmission line, ensures the safe operation of the transmission line, and fully realizes the on-line electrochemical measurement of the workpiece of the transmission line. The purpose of quickly measuring the corrosion rate of metal components of power grid equipment can be realized.

The invention relates to the field of automatic calibration, and discloses a material pick-up area calibration system and a pick-up system of a cutting machine and a calibration method of the material pick-up area calibration system. The material pick-up area calibration system comprises a projector, light sensors and a controller. The projector is arranged above a pick-up area and used for projecting boundary images to the pick-up area. At least three light sensors are arranged on the boundary of the pick-up area, the different light sensors are arranged at different boundary positions of the pick-up area and used for detecting light brightness, and when the detected light brightness exceeds a preset value, signals are transmitted to the controller. The controller is used for adjusting the projection direction of the projector till the signals from all the light sensors are received. According to the implementation mode, calibration on the material pick-up area of the cutting machine can be accurately and reliably achieved, that is, the actual boundary positions of the pick-up area can accurately correspond to all the boundary images projected by the projector to the pick-up area, and the problems generated by uncalibration of the boundary positions of the pick-up area are reduced.

A shooting control method, device, and control device, wherein the method includes: acquiring an information set including at least two sets of shooting information, and the shooting information includes: shooting position information and shooting angle information when a target object is shot (S301); The information sets at least two groups of shooting information selected, and determines the position estimation information of the target object, wherein the positions corresponding to the shooting position information in the selected groups of shooting information are different (S302); generating a shooting adjustment instruction according to the position estimation information to adjust The camera device: the shooting adjustment instruction is used to adjust the shooting angle of the camera device, so that the position corresponding to the position estimation information is within the field of view of the camera device (S303). This method can effectively avoid the problem of image recognition operation error caused by the occlusion of the target object.

The invention provides a Byzantine failure tolerance method for improving reliability of a wireless Mesh backbone network. The method comprises search and establishment of a Byzantine unit, data backup and failure tolerance. A Byzantine algorithm provided by the application improves the conventional routing protocol, and selects corresponding node data information to perform backup aiming at network attack behaviors of different conditions or abnormal conditions of nodes. When the attack behaviors occur, certain information of the attacked nodes is tampered, or pseudo nodes appear in the network and the nodes are subjected to human failure, the routing protocol fused into the Byzantine principle can acquire accurate node information by judging the backup information of other nodes in the Byzantine unit of the abnormal nodes so as to suppress interference, enhance the failure tolerance capability of the network and promote the reliability of the wireless Mesh backbone network.

The embodiment of the invention provides a control method and device of a terminal. The method includes the steps that when the screen of the terminal is lightened, the illumination intensity of the environment where the terminal is in at present is detected; when the illumination intensity meets specified requirements, identification information of candidate applications is output on the screen of the terminal; then, first operation information of a user on the identification information is acquired, and a target application is determined according to the first operation information; then, the terminal is controlled to start the target application. Therefore, by means of the technical scheme, the problems that in the prior art, the steps of starting a target application are complex and the starting efficiency is low can be solved to some extent.
